Dot Jot Brainstorming: #3

Essential Question: How does fangs, senses, sexual dimorphism and signals affect the mating & courtship of tarantulas?

Foundation Question: What are the main contents of courtship in tarantulas?
NOTES (In own words; one line long)	SOURCES (Author’s Last Name or “Full Article Title”)
Main Idea 1: Mating Hooks & Fangs
Hooks beside pedipalps Holds up fangs wile pedipalps transfer sperm Also is used to push her body up to be able to transfer	(NatGeoWebisodes).
It’s 50/50 the hooks will keep him alive during mating The fumbling of pedipalps and legs may result to death From overstaying his visit during contact He must try his BEST to accurately slide in bulb and inject fast	(NatGeoWebisodes).
Males escape as fast as possible to survive, dads don’t help offspring Only a meet and greet then leaves forever (might mate again)	(NatGeoWebisodes).
Once Ms are desperate, they’ll proceed even if the F doesn’t want sex Ms will position F for sex, but females will most likely kill/eat	(Harris).
Main Idea 2: Males & Females & Sexual Dimorphism
Females are bigger to produce offspring (dimorphism) to ovulate Certain areas are much bigger than other gender (most parts) Which could show partner gender & species much easier Bad eyesight & senses in general	(NatGeoWebisodes).
Females have a slot on abdomen, where pedipalps inject sperm Large amounts of offspring per egg sac Egglings 50 to hundreds depending on specie of tarantula	(NatGeoWebisodes).
From the ends of the pedipalp  from the “bulbs” (M genital) These bulbs are red-fat-ish that have slim ends	(NatGeoWebisodes).
M is brighter in color, more extended legs & more active than females Males to mature - 1.5 years, females - 2 years (estimatedly) M’s are highly active when DNA is filled in pedipalp- even day	(Bagaturov).
If early female is located & male found the mate, he’ll come back To wait for the immature female will molt then to mate	(Harris).
Main Idea 3: Signals - During Courtship/Mating
Males are the ones to dance for her by beating/drumming Vibrations are sensitive & that they’re not predator nor prey	(“Tarantula Reproduction”).
No marriage behavior before mating such as cuddling, preening, etc.	(Bagaturov).
Once females are aggressive, they put fangs in the air maybe legs too May lead to cannibalism/injury of male - no success of sex	(Bagaturov).
NOT aggressive, female would position herself for sex - success at sex Would not show fangs, slow and possibly doing drums too Would also walk up to partner slowly as is male	(Bagaturov).
DIRECT QUOTE: “...solitary animals, meaning they live and feed on their own, and they are generally spread out over a wide area, making an available female relatively scarce. The male spider has the daunting task of tracking down a sexually mature, receptive female in the area before other males can get there” (Harris, Tom).
